How to better data center migration

Data center migration is not a trivial matter, which is very different from the relocation of enterprises, and the relocation measures in the data center include decomposition, storage, transportation, and re assembly equipment. Migration data center must consider other important factors, that is to ensure that customer data can be accessed in the conversion process. If you need to transfer the data center business has never experienced such a challenge, please be sure to get engaged in the service of the company to help customers, to avoid business interruption, which caused serious influence on the enterprise's business and reputation. Careful planning and preparation is critical to the successful migration of data centers, and understanding these options is a good start.

Data center migration has two basic modes: push / pull migration (physical mobility) and virtual / application migration.
Push / pull migration
Push / pull migration is usually in the smaller data center, with high risk, low price, simple features, push / pull migration at the most basic level can be easily decomposed data center components, transported to a new location, and re combination of them. The most obvious disadvantage is the data center can not be used in the migration process, once the components are disassembled and reassembled, there will be a large degree of unpredictability, these may be facing a major problem depends on the customer's data center.
To ensure the successful implementation of the push / pull migration method, data center employees need detailed list records of components in each rack so that they can be reinstalled in the same slot in the new location. In the mobile Internet connection and mapping before setting the correct power distribution is also very important. After migration, once the new data center is operating on line, it is necessary to pay attention to the utilization of electricity, and the power of the whole data center infrastructure should be balanced from UPS to rack level. In addition, optimizing rack level airflow is critical for ensuring adequate environmental conditions and maximizing efficiency.
In the process of physical relocation, need to consider several factors. It is important to set the static and dynamic load ratings of the rack, if the rack is moved to a dense device. The weight of the dynamic load is light, and if the overload is the weakest part of the caster, the frame structure is prone to malfunction. The pallet rack should be installed in the anti vibration, then a long-distance transport truck. Even tiny bumps and bumps can have bad effects on machine equipment that has never been moved before. Because the data center mobile components are rarely in use, so it is not usually install tip protector, whether mobile or anchored around the equipment in the truck, the frame is easy to tilt on the move, the low cost of hardware can prevent the frame drop, thus saving thousands of dollars.
Whole migration
Data center migration takes a long time, and is more detailed than push / pull migration, and there are no simple steps or shortcuts to follow. Instead, you need to replicate to create the same data center so that the business can run normally during migration. The computer environment of the data center is the same, and at least three tests of network connection and application should be carried out before migration. Once the test results are satisfactory, the data center environment is frozen (this is an image metaphor). The hardware environment, network environment and the computer environment will remain static, until the completion of the migration.  Updating records and applications may occur after migration, and it is important to avoid updating the firmware at this point to prevent conflicts. Copy the data center to ensure the normal operation of the continuous time and careful testing environment is the overall migration than the push / pull migration mainly due to more time-consuming and more expensive, but can ensure the effective transfer completed, and minimizes the problem of data center tenants.
Once the migration is complete, some abandoned data center equipment must be dealt with. For example, erasing disk data, and remove the memory array to protect data security. Some of the hardware as waste disposal, such as large server rack.  For more advanced processors, storage arrays, network devices, and structured cabling, they can be refurbished and resold.
The best practice of migration
Both push pull migration and overall migration are suitable for data center migration with the following best practices:
Planning. The first step of any successful migration is to ensure that the delivery path is clear from the beginning of the migration until the completion of each device is deployed at the destination.
Hiring managers who know the whole process. In order to ensure smooth migration, the responsible managers need to make a difficult decision, answer the questions of the personnel, and record the details in the process.
Unless absolutely necessary, otherwise can not change the transfer date. The aim is to avoid confusion. More importantly, spend a certain amount of time pre planning all the details so as not to make hasty decisions at the beginning of the migration.
Tracking stroke. The company has always wanted to know the itinerary of the migration. Enterprises can use transport trucks loaded server rack using RFID, and GPS technology has been used to track the itinerary.
The use of air conditioning system with trucks to protect equipment. Almost every data center component needs a good cooling, and an air conditioned truck can minimize device failure even if it is transported in a very short distance.
